The planetary breakup that shook the solar system! In 2006, astronomers officially demoted Pluto from planet status to "dwarf planet" after discovering dozens of similar objects in the Kuiper Belt. The meme perfectly captures that one friend who refuses to accept scientific consensus with their emotional "Pluto is still a planet" stance, only to be confronted with the cold, hard astronomical reality: there are about 70 other Pluto-sized objects out there! Sorry, Pluto defenders - size matters in planetary classification, and your fave didn't make the cut. The International Astronomical Union had receipts!
